Thanks to Lump and a couple others we found a pretty major bug with 2.1.2 that would cause areas to seem to revert.

2.1.3 addresses this issue and should fix any worlds affected. It should also fix any misplaced spawn points.

Because we had the feature done, 2.1.3 also includes "Host Mode" now. If you're serving an MP game, you can set yourself to Host Mode the same way you toggle Observer on and off for others. While in Host Mode, you won't be able to interact with the game, just like an Observer wouldn't, but you also won't breathe, take damage or be irradiated, effectively allowing you to set Host Mode and walk away, leaving the game running while other clients play on your world.

This is uploaded to BMT and should be available.We are uploading to Desura, but as 2.1.2 never even made it to approval, we expect this won't hit Desura until sometime Sunday (when they return to the office) ... we have no control over this process or its speed.

These changes are wrapped into the Xbox update we will be pushing, hopefully early next week. These are the kind of bugs that destroy the Xbox build because we can't insta-patch it like on PC (it would be stuck in the wild like that for at least 9 days, and more like 20), so we're happy we're catching them here now before we even do the Xbox release. This leads to much more stability on Xbox releases. It is also one of the reasons it may be worth the price difference to own the PC version.
